How this service works
Machine-callable x402-paid utilities for autonomous agents.
Output
A JSON object with per-check results including: a boolean `present` flag, the `occurrence_count` of how many times the text was found, up to a handful of `contexts` (surrounding text snippets), and whether the count was capped. Also includes HTTP metadata (status code, latency, content type), the final resolved URL, a SHA-256 body fingerprint, a timestamp, and a scope disclaimer clarifying this is source-text presence only (not factual truth or semantic equivalence).
Example use cases
Verify product claim on landing page
“Check whether the product page at https://acmecorp.com/products/widget mentions the phrase 'FDA approved' and also whether it says '30-day free trial' — I want to know if both claims are actually there before I reference them in my report.”
Confirm legal disclaimer presence
“Can you verify that https://startup.io/terms contains the text 'arbitration clause' and 'limitation of liability'? I need to confirm those provisions are actually on the page.”
Monitor competitor messaging
“Check the page https://rival-brand.com and tell me whether it currently mentions 'AI-powered' and 'enterprise ready' — I'm tracking what claims they're making publicly.”
Technical details
Endpoint
POSThttps://creator-desk-x402-isolated.onrender.com/v1/web/evidence?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, verifiable, source-text check of whether specific phrases or strings appear on a public webpage — particularly for compliance checks, claim verification, content auditing, or monitoring. It is ideal when you have exact or near-exact text to look for rather than semantic meaning. Prefer this over general web scraping when you only need presence/absence and context snippets rather than full page extraction, and when you need a content fingerprint for auditability.
Side effects
- Non-HTTPS or non-HTML URLs will fail or return unexpected results
- Pages behind authentication or paywalls will not be accessible
- JavaScript-rendered content may not appear in the inspected source HTML
- Very large pages may have body bytes capped, potentially missing late-occurring text
- Redirects are followed but the final URL is reported, which may differ from input
- Rate limiting or server-side blocking of the crawler IP may cause HTTP errors
- Malformed or unreachable URLs will produce HTTP error status in the response
